heat recovery ventilation

An independent air quality report, funded by the UK Technology Strategy Board, currently in draft format but soon to be published on the bere:architects research pages, has produced some striking evidence for the ability of properly designed, properly installed and properly commissioned heat recovery ventilation to significantly improve indoor air quality, particularly in urban locations.

After less than four months these pollen filters, from one of our heat recovery ventilation units, have trapped so much London air pollution that they need changing for fresh filters. By comparison, in a German city, where urban air quality is very much better, the same filters need changing only once a year. German vehicle testing (with the introduction of a colour-coded 'flag' system) would prevent a large proportion of UK vehicles from entering a German city.
